Country Performance

By zooming in a bit further, GAPI offers a glimpse into the marine finfish aquaculture industries of each of the 22 countries assessed. By grouping performance by country, GAPI distinguishes those countries or regulatory schemes that are best (and worst) at addressing the major environmental impacts of marine aquaculture.

For instance, China’s GAPI score (normalised per mT of production) is 32, 27 points below the global average for all countries and well below ideal performance (100). Since GAPI assesses eight different species produced in China, which comprise 61% of all of China’s marine finfish production, users can have some confidence that China’s GAPI score is a strong reflection of its marine aquaculture industry.

Country Normalised and Cumulative Scores

Similarly, users can gain an understanding of the effects of scale of production in a country. For instance, Chile’s score per mT of fish produced is 65. Its cumulative score (30) is less than half its normalised score, demonstrating the effects of the large scale of its salmon industry.

Country scores are a powerful tool for regulators looking to compare their country’s overall performance to that of their peers. Normalised country scores are especially useful to regulators interested in comparing their performance to that of other countries, regardless of the scale of their production, where cumulative country scores provide insight into the overall impact of a country’s marine aquaculture industry. Country scores can also be dissected by indicator, which enables a regulator to assess where it might focus its efforts (e.g., reduction of wild feed inputs or greater treatment of discharges) to achieve the greatest ecological improvement (i.e., higher GAPI score). Similarly, regulators can compare their country’s performance across species to identify trends and evaluate the efficacy of marine aquaculture regulations in particular impact areas.
